Guys, this thing is only rated to full power at thirty degrees. I've spoken about this kind of thing before, but not for a while, so here's my position on this: I have no use for anything that can't do full power at forty degrees or better, and I review these units accordingly. Computer cases routinely see temperatures higher than thirty at the power supply intake, and this becomes more and more of an issue the further south you live, depending on whether or not you're buying this budget unit so you can afford to run the AC.
It also becomes more of an issue depending on where your unit is located. I have family with computers next to heating vents, because that's the only place available to put them. Guess what that does to a Canadian computer? Most of their cases don't have the newer layout where the power supply pulls room temperature air in from underneath the case, so those power supplies are taking in air heated by the vent and the computer hardware. Thirty degrees? Ha!
No, folks, thirty degrees just doesn't work for me. A unit this heavily de-rated is likely only good for 650W at a more reasonable forty to fifty degrees. It may be a perfectly decent little unit, but my hot box will not stay cool enough to make this unit happy. This is by design - my methodology is to get these things to at least forty whenever possible, because that's the lowest temperature I personally expect to get full power out of a unit. Forty is more than reasonable, even for a good budget unit.
Really, here's what it comes down to... this unit has to pass hot box testing, or there will be scoring repercussions on page six. I haven't had to use those particular scoring rules in a looooong time. Corsair, I hope you had CWT give you overtemp protection, because I think this unit is going to need it.
